b) The "above list" of pH values is not provided in the image. However, the typical pH values for these substances are: (i) Lime water* (calcium hydroxide solution) is a strong base. Its pH value is typically around $\boxed{12-13}$. (ii) Pure water* is neutral. Its pH value is $\boxed{7}$. (iii) Vinegar* (acetic acid solution) is an acid. Its pH value is typically around $\boxed{2.4-3.4}$. c) The specific pH value for the solution is missing from the question. The color of a solution when tested with a universal indicator depends on its pH value: pH 0-3 (strong acid): Red pH 4-6 (weak acid): Orange to yellow pH 7 (neutral): Green pH 8-10 (weak base): Blue pH 11-14 (strong base): Violet to purple
